Problem solved! I had no luck finding an SSEi muffler so I bought a muffler for a 95 Firebird, 3.8 V6. I'm really happy with it. It'* just a little louder than the stock SE muffler inside the car but it sounds louder than the sock setup. The muffler I used is a Walker 18375 and it ran me $38 from NAPA. I added two 90 degree elbows, a universal hanger, all needed clamps and two cuplers. The total came to about $70. It'* a 2.5 in and two 2.25 outs. It'* perfect! Here'* a few pics...
I'm buying some chrome tips next weekend.... I'm thinking of 45 degree cutoffs.
